LOCK.

SPECIFICATION forming part of Letters Patent No. 626,341, dated June 6, 1899.

Application filed December 2l, 1898. Serial No. 699,891. (No model.)

To all whom, t may concern,.-

Be it known that I, BYRON PHELPS, a citizen of the United States, residing at Seattle, King county, Washington, have invented certain new and useful Improvements in Locks, of which the following is a full, clear, and exact description.

My invention relates to improvements in locks and locking-latch mechanism; and my object is to improve and simplify the construction of the same.

In the preferred embodiment of my invention shown in the drawings, Figure l shows a plan view, partly in section, of my improved door-lock. Fig. L shows a horizon tal sectional view of the same, the parts being broken away. Fig. 3 shows a vertical section on the line X Xof Fig. 1, the rod-spring having been removed, looking in the direction of the arrows. Fig. 4 shows the roll-backs in detail in their normal operative position with relation to the lock-rod. Figs. 5, 6, 7, 8, 9, 10, 11, 12, and 13 show details of other parts of the device.

In the preferred embodiment of my invention shown in the drawings, A represents a frame of the lock, having preferably integral transversely-extending spindle barrels or bearings a d', connected by an integral bridge a3.

B is a latch-bolt operatively connected to the knob-spindles by a shoe b, having a yoke b and lugs b2 projecting therefrom.

O O are escntcheons or side plates, preferably separate from, but fitting over the spin- (lle-bearings.

My lock as a whole is preferably designed to be introduced into a notch in the stile of the door, and some of the parts above described are broadly claimed in my former application, filed March l0, 1897, renewed December 5, 1898, Serial No. 698,371.

D is a knob preferably hollowcd ont and formed in two parts, as shown, and having a hollow spindle d, attached to the inside of the head of said knob. rlhis knob and spindle are shown more in detail in Fig. 6.

d', Fig. 2, is a groove in the frame, forming an abutment for the retaining device, and d2 is a seat, preferably a circumferential groove in the knob-spindle, adapted to register with the groove d', so that a retaining device, such as a pin (Z3, may be inserted between the same and hold said knob and spindle in place. By circumferential I do not mean that the groove must extend necessarily entirely around the spindle. The end of said spindle is transversely slotted through both sides thereof, as shown at d, and said spindle is also provided with a longitudinal slot d5 through one side thereof. A roll-back F, having a round hole and lateral projections, as shown in Fig. 4., is inelosed in the end of the hollow spindle, the projections passing through and being preferably at all times retained in said notch d4.

G is a lock-rod, preferably of angular, in this embodiment of a square, cross-section, inclosed in the hollow spindle and extending through so as to be rotatable in the said rollback F. This rod has a lug g and a projection g. The projection g' is surrounded by a washer g2, which loosely fits the inside of the hollow spindle, and g3 is a spring pressing against the head of the knob and its washer to press the rod toward the right.

H is a finger-cam, preferably held between the knob and lateral spindle-bearing, extending transversely outside of said spindle and having a longitudinal extension h, which carries a cam-face 7L'. By the rotation of this finger-cam the cam-face will act upon the lug g and operate the lock-rod.

E is a second hollow knob, preferably formed of a base e5 and a cap e6. The base e5 has a hollow spindle e, held in the spindle-bearing a by a pin-and-groove connection, as heretofore described in regard to the spindle d. These spindles d e are preferably not joined together; but it will be obvious that some of the functions of the mechanism herein disclosed could be performed if said spindles were so joined together. The spindle e is shown more in detail in Fig. 5 and has in the end thereof a transverse slot through both sides thereof, e4. This slot may be deeper than the slot b4 in the spindle d, for the purpose hereinafter set forth.

K is a second roll-back, having a square hole therein, as shown in Fig. 4, and projections to contact with the lugs b2. This rollback is held in the end of the hollow spindle,

. through the slot e4; but said roll-back is thinner than the depth of said slot and may therefore be moved longitudinally in the same.

0.2 is a slot through both sides of the inner extension of the spindle-bearin g a, preferably just deep enough to contain the projections of the roll-back K. The spindle e when in 'its operative position extendsinward, or to the left of the end of this spindle-bearing, as shown in Fig. 2; but the slot e4 in the end of the spindle extends to the right into the end of the bearing ct and is adapted to register, when in one position, with the slot a2. The roll-back K can then be moved outward, or to the right, as shown in Figs. 1 and 2, and the projections thereof will enter the slots c4 and a?, which will result in locking the spindle c from rotation. This movement of the roll-back K is accomplished by the longitudinal movement of the rod G. This rod has a smaller and preferably rounded portion g4, by cutting away which shoulders g5 and g6 are formedon the rod. The roll-back K is slipped onto the angular rod, the angular hole therein allowing it to just tit the angular outline of said rod; butwhen it reaches the part g4 and the rod is then given a part of a turn, as shown in dotted lines in Fig. 4, the shoulders g5 and g6 on the rod, formed by cutting away the rod to form the rounded portion g4, will not then register with the hole in the roll-back K and the roll-back will then be locked from longitudinal movement of said rod, and by the longitudinal movement of the rod said roll-back Vwill be bodily moved in one direction or the other. As before stated, the rod is rotatable in the hole in the roll-back F. Therefore when the finger-cam H is rotated the rod will be moved in one direction or the'other and will.

carry the roll-back K with it, but will not displace the roll-back F.' The movement of this linger-cam `will therefore serve to lock or unlock the knob E. The parts are shown -in their locked position in Fig. 2, the finger-cam having been rotated so as to allow the spring g3 to press the lock-rod to the right, carrying the roll-back K with it farther into the slot e4 and also into the groove a2 in the relatively stationary spindle-bearing ct. Although the right-hand knob E is in this position locked, the left-hand knob D can still be rotated and.

throw back the latch, because although the roll-back K is fixed the rounded part g4 allows the rotation of the rod G relative thereto and a very slight movement given thereto by the rotation of the knob D, sufficient to throw back the latch, will not bring said angular rodv into the position to register with the angular hole in the roll-back K.

To unlock the mechanism from the knob E-that is, to .rotate one of the roll-backs and throw back the latch when the parts are in the position shown in Fig. 2-1 have provided a preferably pin-tumbler lock L, contained in the knob E. The pin-tu mbler lock fits into a seat e, formed by a projection ew, as shown in Fig. 13, and is fixed relatively to the knob by the lugs cl2,- inclosing the tumbler-casing Z8 at the sides. The other end of the lock fits a seat els, as shown in Fig. 2, and is held in place by drawing the cap c6 toward e5 by the screws e8. The lock has an inner relatively rotatable key-barrel Z, locked by the pintumblers Z6, but releasable, as is common in that class of locks, by the insertion of a k'ey. The projecting end of this barrel is shown in dotted lines at Z7. A cap Z (shown in detail in Figs. 9 and 10) is slipped over this projection Z7 and fixed thereto by a pin Z2, passing through both of the holes. This cap has a hole Z3 in theend, into which projects the end of the rod G. When the knob E is locked as shown in Fig. 2, the rotation of the knob D, and consequently of the rod G, would not be possible, as the end of the rod projects into this cap, unless some play were allowed between the end of the same and the cap, because said cap is then fixed relatively to the knob E, which is then locked. To allow for this play, the angular end of the rod is fitted to a hole in the cap, as clearly shown in Fig. 9, and then the portions Z4 are cut away in said cap, so as to allow a slight rotary movement of this rod before the corners of the rod will come in contact with the shoulders Z5.

When the parts are locked, as shown in Fig. 2,by-a keyinserted into the key-barrel through the hole c7 in the knob-cap, the key-barrel may rotate, although the knob E remains fixed, which will rotate the cap Z', and as the barrel'and cap are further rotated the shoulders Z5 will come in contact with the corners of the angular rod, and upon a still further rotation of the key-barrel the rod will be rotated, carrying with it the spindle CZ and the roll-back F, which will throw back the latch. The rod is thus connected with the roll-back F to operate the same, in the present embodiment not directly with it, but through the medium of spindle CZ. When the key-barrel and other parts are allowed to come back to their position, (shown in Fig. 2,) the key may then be withdrawn, and in this way a safe and yet convenient locking means is provided for the outside handle of a door.

Where screws or other attaching means are used in plain sight outside of the escutcheonplates, the same may be tampered with or removed and the knob stolen or the locking or latch mechanism destroyed. It is therefore desirable to conceal or do away with such attaching means. As shown in Fig. 2, the knob E is formed of two parts, a base c5 and a knob e6, held together by screws e8, passing through holes in the base and into the threaded portion e? in the cap. To cover up and conceal these screws, I have provided a rosette elo,

abutting against the base c5 and a shoulder on the spindle-bearin g. This completely conceals the screws and prevents any unlawful tampering with the same.
